Thank you for more detail about your setup.
The shock length 64mm w/stock shock tower would be ok. But i would suggest using 4mm hex in the front along with 0.5mm spacer (each side) and 5mm hex (kit stock) in the rear.
Also, i would try inner shock mounting hole on the rear tower that would be #3 with 2mm inner camber link height.
Most importantly for carpet racing in general, way of applying traction additive is the key. I think you should try many different ways of additive like more front tire additive or longer time and find what the best drive feel for you. This should make more drastic change on the drive feel than finer setup changes.
hope it helps a bit.
